Support that multiple keys are mapped to the same class via @JsonSubTypes.Type

[LennartH]

The following annotation example would result in an error that the type for Simple2 couldn't be found.

@JsonTypeInfo(use = Id.NAME, include = As.PROPERTY, property = "type", visible = true)
@JsonSubTypes({
    @JsonSubTypes.Type(value=ComplexImplementation1.class,name="Complex1"),
    @JsonSubTypes.Type(value=ComplexImplementation2.class,name="Complex2"),
    @JsonSubTypes.Type(value=SimpleImplementation.class,name="Simple1"),
    @JsonSubTypes.Type(value=SimpleImplementation.class,name="Simple2")
})
public interface Interface {
    enum Type {Complex1, Complex2, Simple1, Simple2}
    Type getType();
    ...
}

I think the problem is the way the concrete TypeDeserializationInfo is generated. The resulting method would look like this, ignoring the second type key for SimpleImplementation:

@Override
protected TypeDeserializationInfo<Interface> initTypeInfo() {
    return new TypeDeserializationInfo(JsonTypeInfo.As.PROPERTY, "type")
		.addTypeInfo(ComplexImplementation1.class, "Complex1")
		.addTypeInfo(ComplexImplementation2.class, "Complex2")
		.addTypeInfo(SimpleImplementation.class, "Simple1");
}

Could it be, that the generator uses the concrete implementations of Interface as loop condition and breaks after every implementation was mapped to a key?
